BT30!) ASSEMBLING FIBER SHIPPING CASES.-

Application filed December 30, 1924. Serial No. 758,923.

To all whom it may concern:

Be it known that I, HERBERT It. Buss, a,

citizen of the United States, residing at Niagara Falls, in the county of Niagara and assembling fiber shipping cases, or shipping cases made of similar material.

It is the object of the invention to afford a method by which shipping cases may be quickly and cheaply assembled.

In the drawings:

Fig. 1 is a side elevation of a machine stitching a shipping case simultaneously at both ends.

Fig. 2 is a plan view of the form that can be used in my method.

Fig. 3 is a section taken on the line 3-3 of Fig. 2.

Fig. 4 is a section taken on the line 4-4 of Fig. 2.

Fig. 5 is a perspective of one of the forms that can be used.

Fig. 6 shows the box in the form.

Fig. 7 is a section taken on the line 77 of Fig. 6.

One form of shipping case which has lately come into quite extensive use is the three-blank, flush-end ship ing case such as isshown in my Patent 10. 1,375,127, of April 19th, 1921, or the Lemon Patent No. 1,428,597 of September 12th, 1922. It is the object of the present invention to provide a method of assembling these shi'ping cases so that they can be expeditious y tempora rily held together and stitched, preferably by simultaneous operations at both ends.

A shipping case such as I have referred walls a, b and bottom wall 0, with narrow flaps a, b and c at each end of these walls. At each end of the case is a separate end blank (1. The problem is how to. set these cases up and stitch them together expedi-' tiously, for obviously the value of such a shipping case as opposed to other shipping cases depends not only in the amount of.

blank material, but the actual labor cost, and the machine costin setting the ease up. Cases ofthis character have been assembled by first successively turning down each flap at each end and then running lt'over an anvil, and'under a stitching head. This is a clumsy hand operation for the reason that until several of the flaps have been stitched to the end blanks, the case has no definite shape and is hard to hold in the hands. Furthermore, this is a relatively long operation. v

Another method is that described and claimed in my application Serial No. 681,709. That method has the advantage of much greater speed but still is largely a hand manipulated operation and open to that objection.

The present method is an improvement of either of the other two methods inasmuch as all the parts are temporarily held together, in box shape. This enables much easier and quicker stitching at each end at one time and has the further advantage that with the proper machine both ends may be simultaneously stitched together, thereby greatly saving in time and labor costs. The temporary clamping'of the several blanks together in box form, or temporarily holding, might. conceivably be performed by two pairs of hands, but it is obviously most advantageously performed by a proper device for this purpose. I prefer to employ a form such as is shown in Fig. 5, which is sim ly aframe provided with a pair of side hol ing wings g, and a pair of narrow endholding flanges 7. These flanges and wings are an integral part of the frame k, which is rectangular in shape and to which is riveted the four legs 5, so that the device may be easily icked up from the floor. However, it wi 1 be apparent that quite a different device or clamp might be used, and that for that matter the whole 0 eration might be done by several pairsof ands properly placed to hold the parts temporarily while the ends are being stitched.

In present day fiber-creasing machines, -it is usual to make two creases wherever-corners occur. This forms a sort of recess when the blank is folded up to form the corner. Such a recess is shown at a: in Fig. 3, and y in Fig. 7. The form is set down on the floor. The body blankis folded up with the sides a and b engaging against the side-holding win s 9 of the form and the flaps 0 a and I? bearing against the end holding flanges f as is shown in Fig. 6; these flaps a, b and c tend to resist this turning in and consequently they bear tightly a ainst the end holding flanges of the form.

owever, it is to be noted that the flaps a bottom ends which bear on the inside of the end holding flanges 0. However, this is suflicient to keep thesefiaps turned toward each other toreceive the first staple. After the first staple has been driven in, or" course thiswill hold the flaps against the end blanks.

ll hen the main body blank, together with the flaps, have been positioned as indicated, then the end blanks d are slid down inside the flaps (r 5 in the recesses 3/ of the creases until they finally settle in the creases a: at the bottom (see Fig. 7 and Fig. 3).

It will be apparent therefore that in the clamping or temporary holding action, recesses of the creases hold the end blanks on the inside and thereby cooperate with the outside form. They therefore take the place of a iornr on the inside or the use or human hands on the inside.

It will be apparent also that a box may he quickly slipped into this form and held in position for stitching with the blanks ten porarily clamped together. It is obviously much easier to manipulate the case over the anvil. it is possible, as shown in Fig. 1, to work on both ends of the case simultaneously, or for that matter, it is conceivable that fasteners could be driven in by several hands at even more than two places at one time. It is therefore evident that the method can be practiced separate from and apart from the particular machine shown in Fig. 1, which is desirable for speeding up the setting up operations.

What I claim is:

1. A method for assembling shipping cases constructed of fiber board or equiva: lentmaterial comprising a body blank and one or more other blanks, which method comprises the setting u of the blanks and holding them temporarily together in box form, then while so holding placing the box over an anvil and driving metal fasteners thereinto to stitch the other blanks to the body blank. f

2. The method oi assembling shipping cases of fiber board or equivalent material which comprise a body blank and one or more other blanks engaged together by shal- 7 low flanges, which method comprises the holding or the blanks together temporarily in box f rnnthen applyingthem over the anvil and stitching the flanges to the adjoining blanks to completely assemble 3. The method of assembling fiber shipping cases constructed of fiber or equivalent board, which comprises three blanks includincome ing a body. blank and two end blanks secured together in flush relation by shallow flaps, which method comprises the initial setting together of the blanks with the flaps to form a temporary box structure, then placing the same over the anvil and stitching the flanges to the adjacent blanks.

a. The method of assembling fiber shipping cases constructed of fiber or equivalent board which comprise threeblanks including a body blank and two .end blanks secured together in flush relation by shallow flaps, which method comprises the initial setting together of the blanks with the to form a temporary box structure, then applying the same over a pair of anvils and simultaneously stitching both ends in t re case by driving fasteners siniultaneousl'5 through the flaps the end blanks at ends.

The method of assembling fiber board or equivalent material shipping cases which comprise a body blank and two end blanks to be set in flush with the body blank with shallow flaps on the body blank turned over the end blanks, which method comprises the initial setting up and temporarily holding of the-box together and then applying the box over an anvil and driving metalliciasteners through the flaps and the adjacent end blank.

6. The method of assembling 'fiber board or equivalent material shipping cases which comprise a body blank and two end blanks to be .set'inflush with the body blank with shallow flaps on the body blank turned over the end blanks, which method comprises the initial setting up and temporarily holding of the box together-and then applying the box so temporarily held over a pair of anvils and simultaneously driving metallic fasteners through both ends to stitch the flaps at both ends contemporaneously to the two end blanks.

7. The method of assembling shipping cases of fiber board or equivalent material, which comprises a body blank with one or more other blanks engaged together by shallow flanges, which method comprises the holding of the 'one lank and the turning over of all the flanges of the other blank and holding them against said first blank, then applying these blanks with the turned over .fianges over the anvil and stitching such flanges to the blank over which they lie.

In testimony whereof I have alilxed my
